Short Answer

There are six people taking a vocational exam with both oral and written parts. Their scores (out of 100) on the written section are given by the vector $\vec{r}=(71,49,87,98,81,63)$ . Their scores (out of 100) on the oral section are given by the vector $\vec{s}=(79,74,82,95,97,66)$ . Find the vector giving their composite score if the written part counts twice as much as the oral part.
